What if we take cobalion and use him as a tank, taking advantage of his 129 base def??

You need 112 speed EVs on him to outspeed adamant 252 Speed kanga, with the 144 being what's left after dumping 252 into Def.
Can survive anything at +0 and non-SE moves at +2, and if you switch him in on a crunch, the +2 you get from justified will OHKO kanga back.
And if you manage to burn her beforehand...
+2 252+ Atk Parental Bond burned Kangaskhan Earthquake vs. 0 HP / 252+ Def Cobalion: 211-249 (65.3 - 77%) -- guaranteed 2HKO after Stealth Rock
Could even run a balloon or weakness policy on him if you can switch him in on a +0 kanga
Anyone tried anything like this before?
EDIT: forgot parental bond activates justified twice
